(1)php cli方式下获取服务器ip


[php] 
function getServerIp(){ 
        $ss = exec('/sbin/ifconfig eth0 | sed -n \'s/^ *.*addr:\\([0-9.]\\{7,\\}\\) .*$/\\1/p\'',$arr);      
        $ret = $arr[0]; 
        return $ret; 
    } 

function getServerIp(){
  $ss = exec('/sbin/ifconfig eth0 | sed -n \'s/^ *.*addr:\\([0-9.]\\{7,\\}\\) .*$/\\1/p\'',$arr);  
  $ret = $arr[0];
  return $ret;
 }


(2)php cgi方式下 获取 客户端ip和服务器端ip

[php] 
 

[php]
PHP获取客户端和服务器IP地址的函数写法如下: 
[code=Php width=600px]/**
* 获取客户端IP地址
* @return string
*/  
function get_client_ip() {  
    if(getenv('HTTP_CLIENT_IP')){  
        $client_ip = getenv('HTTP_CLIENT_IP');  
    } elseif(getenv('HTTP_X_FORWARDED_FOR')) {  
        $client_ip = getenv('HTTP_X_FORWARDED_FOR');  
    } elseif(getenv('REMOTE_ADDR')) { 
        $client_ip = getenv('REMOTE_ADDR');  
    } else { 
        $client_ip = $_SERVER['REMOTE_ADDR']; 
    }  
    return $client_ip;  
}    
/**
* 获取服务器端IP地址
* @return string
*/  
function get_server_ip() {  
    if (isset($_SERVER)) {  
        if($_SERVER['SERVER_ADDR']) { 
            $server_ip = $_SERVER['SERVER_ADDR'];  
        } else {  
            $server_ip = $_SERVER['LOCAL_ADDR'];  
        }  
    } else {  
        $server_ip = getenv('SERVER_ADDR'); 
    }  
    return $server_ip;  

[/code] 
客户端IP相关的变量  
1. $_SERVER['REMOTE_ADDR']; 客户端IP,有可能是用户的IP,也有可能是代理的IP。  
 
2. $_SERVER['HTTP_CLIENT_IP']; 代理端的IP,可能存在,可伪造。  
 
3. $_SERVER['HTTP_X_FORWARDED_FOR']; 用户是在哪个IP使用的代理,可能存在,可以伪造。  
 
服务器端IP相关的变量  
1. $SERVER_NAME,需要使用函数gethostbyname()获得。这个变量无论在服务器端还是客户端均能正确显示。  
 
2. $HTTP_SERVER_VARS["SERVER_ADDR"],在服务器端测试:127.0.0.1(这个与httpd.conf中BindAddress的设置值相关)。在客户端测试结果正确。  
 
3. $_SERVER['LOCAL_ADDR'] 、$HTTP_SERVER_VARS['LOCAL_ADDR'],测试中,未获得任何结果(测试环境PHP5)。

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
